NEW YORK -- Manager Joe Girardi said that the Yankees will likely make a roster decision regarding injured first baseman Mark Teixeira by Friday.

Thursday's series finale against the Rangers was the fourth consecutive game out of the starting lineup for Teixeira, who has a mild strain of his lower left lat. After Sunday's 3-2 win over the Reds, Teixeira underwent an MRI exam that revealed the injury.

"It's just seeing how he feels after three or four days," Girardi said. "Then we'll decide if we think it's going to be the near future that he would play or we're going to need the 15-day [disabled list]. If it's going to be 12, 13, 14 days, it probably makes sense to get a player here."

Besides receiving a platelet-rich plasma injection on Monday from Yankees team physician Christopher Ahmad, Teixeira has just been resting, hoping to heal quickly.

"I don't think tomorrow's the day," Girardi said on Thursday. "But obviously, you want to feel that there's progress and that he feels better to start doing some stuff. We felt that we'd give him three days without really doing much but treatment, and then we'd see where we're at."
